The transaction was executed under a Rule 10b5-1 trading plan adopted on 03/10/2025, indicating it was pre-scheduled rather than discretionary. After the sale, Franchi retains 65,530 shares, a decrease of about 3% of her direct holdings, maintaining a sizable equity position that continues to align her interests with shareholders. No derivative securities acquisitions or dispositions were reported in this filing.

Disc Medicine, Inc. (Nasdaq: IRON) has filed a Form 8-K announcing the election of Nadim Ahmed to its Board of Directors, effective 14 July 2025. Ahmed will serve as a Class I director until the company’s 2027 annual meeting and thereafter until a successor is elected or he resigns. Under the company’s non-employee director compensation policy, he will receive $40,000 in annual cash fees (paid $10,000 quarterly) and a non-statutory option for 20,000 shares of common stock priced at the market close on the effective date. The option vests one-third on the first anniversary and the balance in equal monthly installments over the next two years, contingent on continued service. The filing notes no related-party transactions involving Ahmed and states he will enter into the standard director indemnification agreement. No other material financial or operational disclosures were provided.

• Post-transaction ownership: 161,828 common shares held directly and 150,175 options remaining.
• The underlying option grant (09/13/2031 expiration) vests in 48 equal monthly tranches that began on 09/01/2021.

The filing represents a relatively small (< 4%) reduction in Quisel’s equity stake and appears routine, given the pre-arranged 10b5-1 plan. No company fundamentals were released.
